This method not only takes a long time but also has high costs, seriously affecting the normal use of the vehicle. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and provide a trailer saddle support leg that can freely adjust the height of the support leg according to the vehicle load situation, reduce the maintenance cost, and ensure that the vehicle can be used normally quickly.

[0004] The technical solution adopted by the utility model to solve the technical problem is:

[0005] A trailer saddle support leg includes a support leg body and a shaft hole. The shaft hole is arranged on the side surface of the top of the support leg body. An arc-shaped reinforcing rib is arranged on the top of the support leg body. Both ends of the bottom of the support leg body extend outwards to form mounting parts. The end of the mounting part is provided with a first support handle integrally formed. A bottom plate is arranged below the support leg body. Screws are respectively arranged at both ends of the bottom plate. The screws penetrate through the mounting parts of the support leg body, and nuts matching the ends of the screws are arranged. An adjusting plate is arranged between the support leg body and the bottom plate, and the adjusting plate is located at the position between the two screws.

[0006] A U-shaped bracket is arranged on the bottom plate outside the screw, and the first support handle passes through the U-shaped bracket horizontally.

[0007] Both ends of the arc-shaped reinforcing rib extend to the side surface of the support leg body, and a transverse support rib is arranged between the arc-shaped reinforcing rib and the side surface of the support leg body.

[0008] Both ends of the bottom plate are respectively provided with a second support handle integrally formed. The second support handle corresponds to the first support handle up and down, and mounting holes are correspondingly arranged on the second support handle and the first support handle.

[0009] A groove is dug on the top surface of the bottom plate, and a convex block matching the groove is arranged at the corresponding position of the bottom of the adjusting plate.

[0010] A groove is arranged on the upper end surface of the adjusting plate.

[0011] The positive and beneficial effects of the present utility model are as follows:

[0012] 1. By arranging an adjusting plate between the bottom of the leg body and the bottom plate, the present utility model can increase or decrease the number of adjusting plates according to transportation requirements, thereby adjusting the height of the legs, solving the vehicle transportation problem; by arranging grooves on the top surface of the adjusting plate and the bottom plate, and arranging bumps on the bottom surface of the adjusting plate, the situation that the adjusting plate is not tightly pressed or displaced is avoided, ensuring the installation quality.

[0013] 2. By arranging an arc-shaped reinforcing rib at the top of the leg body and arranging a supporting transverse rib between the arc-shaped reinforcing rib and the side surface of the leg body, the wear resistance of the outer wall of the shaft hole is improved, the service life is prolonged, and the maintenance cost is reduced.
